Given numbers are 605,805,787
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,805,787 is 76657735.
Find LCM of 605,805,787 with Prime Factorization
| 5 | 605, 805, 787 |
| 121, 161, 787 |
Multiply the prime numbers at the bottom and the left side.
5 x 121 x 161 x 787 = 76657735
Therefore, the lowest common multiple of 605,805,787 is 76657735.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
605 x 805 x 787 = 383288675
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
605 : 1, 5, 11, 55, 121, 605
805 : 1, 5, 7, 23, 35, 115, 161, 805
787 : 1, 787
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,805,787, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
805:5x 7x 23
787:787
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 383288675/(1x5)
LCM = 383288675/5
LCM = 76657735
Thus, we can understand that the LCM of 605,805,787 is 76657735.
